OK, so. Operating under the assumption that we still want to get someone to fill the Public Relations (Primary) role next but want to avoid adding fuel to the POD PEOPLE fire...we have fewer choices. I mentioned Chevalier, Miss Militia, and Legend - if anyone else can think of someone who fits, feel free to speak up.
First off, can we expect this role to come with? Well, since it's public relations normally we'd associate that with Charisma, but we'll probably get high Manipulation as well since (a) we're getting the Happy Fun Spike no matter what, and (b) there are two very important charms for shifting public policy towards our own aims that require high MNP. High Appearance goes a long way towards ensuring dominance in social combat so we may see a few 4th Augs for that as well. All told, we can expect CHR 7, MNP 6/7, and APP 5~7. Plus all the actual charms.
What social charms we can reasonably expect* a PR (Primary) alchie to have:
4th Charisma Augmentation (x2) - E1, CHR 1 [1m]. Two charm slots.
1st/2nd Charisma Augmentation - E1, CHR 1 [1m]
4th Manipulation Augmentation** - E1, MNP 1 [1m]
Patriotism-Provoking Display - E2, CHR 3 [1m]
Perfected Union Patterning - E2, CHR 3 [1m]
Motivational Vocoder - E3, CHR 5 [1m]
Pattern Facilitation Module - E3, CHR 4 [1m]
Conceptual Entropy Module - E3, MNP 4 [1m]
Agenda Recalibration Protocols - E3, MNP 5 [1m]
Unobtrusive Repartee Baffles - E2, MNP 2 [2m]
Emotive Aesthetics of the Body Electric - E3, APP 4, PER 3 for submodule [1m]
PLUS
Integrated Artifact Transmorgifier - E2, APP 1 [1m]
Possible Additions (if Autochthon isn't just being thorough, he's being completionist)
4th Manipulation Augmentation - E1, MNP 1 [1m], second of two 4th Augs
2nd Manipulation Augmentation - E1, MNP 1 [1m]
4th Appearance Augmentation (x2) or 5th Appearance Augmentation - E1, APP 1 [1m]
Rogue Cell Isolation Protocols - E2, MNP 3 [0m]
Hierarchical Dogma Lock - E1, INT 3 [0m]
Radiant Iconography Array - E3, APP 2 [0m]
Programmed Catechism Rebuttal - E2, CHR 4 [1m]
Happy Fun Spike and the other charms in its charm tree are, thankfully, gratis so we don't have to worry about charm slots and mote pool restrictions. The ones that require E4 will either be dormant until we hit E4 ourselves, we naturally start with E4 (unlikely) in which case we're also going to pick up Unconditional Imperative Programming (E4 CHR 4 [1m]), or we somehow magically get to use all the POS expansions because REASONS.
So we're looking at 13 charm slots and [13m] committed, bare minimum. 19~20 charm slots and [17m] committed if we include all possible additions. Why yes, focusing on Social does take up a lot of charm space. This means that, assuming we get the full 20 charm slots thanks to picking a very experienced candidate, we have 7 or less charm slots to play with.
That's not a whole lot. Assuming we grab ISF (and a Stam Aug) because it's the best defensive charm available (really helps vs Behemoth and the Simurgh for starters), that means we have even less to work with. Five charms means that any combat capability is going to be limited at best (three charms min for grabbing a PD) so we're going to want someone either naturally tanky or dangerous so we can use charms to shore up the area they're lacking.
*Expect, not want.
**Only one Manipulation Aug is needed, for a few reasons: (1) Alchemical social charms revolve mostly around Charisma so any Manipulation Augs are strictly to meet charm requirements; (2) the highest stat requirement is for a POS expansion, which needs MNP 6; and (3) the two social policy charms (CEM and ARP) function identically to Taboo-Inflicting Diatribe (just with a much narrower area of applicability) which lets you choose between CHR and MNP every time you use it.
