The idea is that Biggs remains behind Tobber. He can receive focus and/or an evade even when stressed.

I like it!

I would probably drop, Tac Jammer, and Enhanced.

Advanced Sensors and Rec Spec on Hobber gives them a little extra heft

Thanks! The idea is, of coarse, to outfit Tobber as a blocker, and with some good flying that will also put his base in the line of fire towards Biggs. And it's cheap, which allows leaving the rest of FSR reasonably intact. Draw Their Fire is sacrificed though.

I'd drop commandos and jammer or scopes for a tactician on Lowhhrick.

You might lack DTF against the worst alphastrikes, and it also means you can spread less. On the other hand you have jynjan, so your Biggs could be even beefier.

The third thought is: how well does a large base fit in with the others?

For one point I love wookie commandos. The commandos let you spend actions on reinforce instead of "wasting" a focus.
