You might want to add more mixer channels, even with the Squid Sample just running the Mix out you are maxing out the STMIX which leaves you less options for patching.
I've recently bought a Doepfer A-138sv for sub-mixing percussion https://www.modulargrid.net/e/doepfer-a-138sv You could kick out the Befaco OUT and the 2x Mults to have room for it.

But don't listen to me if you don't want, these are also my limitations :)

Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
