If an SLN remnant would start launching raids against targets under GA protection, then the economical thing to do would be to attack the bases the raiding force is staging from. Hell, if Theisman had been able to, his best bet would have been to attack Trevor's Star while 8th Fleet was refitting. But as it stands, that would have been far too suicidal.
The Harrington strategy, if we're gonna call it that, does rely on identifying natural break points in the league. It also expects the GA to offer economic and defense incentives for systems or star nations willing to break free from the SL. But that does not automatically translate into having to garrison each and every system thus liberated; Not to mention that some of those systems will come with significant self-defense forces of their own (Maya sector and Renaissance Factor say hello!).
You seem to be assuming a situation where systems free from the SL will require total protection by GA forces. That is simply not the case.
I'd go about it the follwoing way (3-5 years from now):
1) Henke's Meyers sector - style attack on sector capital with a fleet of SD(p)s + support ships.
2) Mop up other SL forces in the sector
3) SD fleet move on to next sector, one SD squadron stays in sector capital
4) BB and SysDefCruiser take over single protectorate systems
5a) System cooperates and stabilizes. Mycroft gets put in. GA CL or DD gets assigned to call for reinfocements if necessary, BB and SDC leave System after a year or so.
5b) System remains hostile. BB and SDC trash shipsyards if there are any; DD gets assigned, BB and SDC leave system,
6) BB and CDC moe to next sector where they are needed
Rinse and repeat ...
P.S. Far out in the verge, occasionally a couple of CAs might suffice from time to time. After all, the SL has thousands of systems - so you use the available BBs somewhat closer to the core where the threat level is higher ...
