TBH, I kind of thought this was what (almost) everybody's already
doing, especially for combat ships.
If you aren't interested in combat, you want the biggest shield possible to give yourself the biggest opportunity to escape.
For combat - sustained combat in particular - regeneration rate is far more important than overall strength.
It's no good starting off in combat with 8,000mj of shield if, once it starts to erode, it's going to take half an hour to recover.
Far better to have, say, 2,500mj of shield that can recover completely in a couple of minutes.
Equally, I tend to find that SCBs aren't much use for mega-shield builds cos, even if you fit a heap of big SCBs, they don't fill the dent in your shield made by cumulative attacks.
They're going to do a much better job (in terms of getting you out of trouble or getting you back
into a fight) by completely restoring a more modest shield.
My Corvettes run a 7C Bi-Weave and a bunch of SBs/GSBs (no SCBs) to boost them and tweak the resistances.
Happily completes wing assassination missions, CZ's and HazRES's without losing a ring of shields (with a constant 2 pips to sys).
About the only time the shield takes a dent is if I go full kamikaze in a CZ... and then it only takes about 4 minutes to recover again, with 4 pips to sys.
