The Mobile reserve are the forces you have based in the Grand Duchy (the heart of the royal desmene). Obviously you have the Royal Guard and the city guard of the three cities and could conscript levies if you need them, but they are also the capital garrison.
So, we would still have a garrison in the Grand Duchy, so it would still be defended. Then I think sending the rest of the mobile reserve out to deal with bandits might be better, since the soldiers left behind would be too little to deal with any significant threats, so we would still have to redirect one of the forces send out to deal with bandits.
Frankly that's nearly totally empty, but in this case a figurative 'nothing' is better than a literal nothing. I say don't commit them just in case of some sudden rioting in the capital or whatever nonsense.
My concern is mostly if this is especially aggressive to the point of problematic-to the point of being a genuine weakness against proper invasion forces. But that's only if this pattern holds up for basically everywhere at once. Maybe once or twice, its OK to get Harlun back on its feet faster, but if Harlun's military enemies (coughcoughmorvakcoughcough) start to notice the pattern, I'm willing to bet it'll bite Vanessa in the ass.
If this sounds kind of unlikely-while Morvak's diplomatic prowess are nearly nonexistent, any general worth their salt would invest into spies-to track enemy positions, obtain the lay of the land. We have no internal intelligence network whatsoever. If Morvak gets wind that our internal reserves are consistently, constantly busy with widescale operations, they can elect to dispatch a concentrated strike force and take heavy casualties if they believe they only need to break the Thornmarch defenses to go deep and do real damage.
But this is only a problem if we make it a habit. I'll accept the plan for now. Maybe even twice. But I'm going to insist we keep considerable reserves for rapid-responses. We shouldn't deal with them forever but the bandits are in fact a military weakness that can be exploited by our enemies if they're made aware of it.
EDIT: Just to be 100% clear I'm OK with the plan, I'm just not OK with this plan becoming a habit for dealing with bandits in the future turns.
Well, at least this turn, one of the forces send to deal with bandits are sent to the Thornmarch, so we would actually have more forces in the area, than normal, so that might make it less of an opportunity to invade, but yes, Morvak might decide to invade, while the mobile reserve is occupied, though as long as the garrison at Thornmarch kept them occupied long enough, then I think we should be able to recall the mobile reserve and send them to assist.
I tried to also make a plan, where all of the mobile reserve is committed.

I am leaning towards asking for concessions from Yarelle Varto, since it has good chances of success, while perhaps just giving the other estate to Reynar Froywell.
