This is a variation on the Damage Control Crew theme.
Let's say each ship starts with crew score/10 damage control teams (DCT). decimals just go up
Bimith has 5, Juyaca 8 Brivoki 13.
The No DC crits take d6 off, crits of the 1-3 location take 1 DCT to stop, 4-5 is 2 DCT to stop & 6 is 4.
When DCT score is reduced to zero you are at -1 to repair. You don't have use them to stop crits.
This represents DCT getting injured & dying by walking into reactors & so on.
If you base it off crew then should be balanced with other ships as ships that are meant to take more have more crew. Simple & easy.
EDIT
Forgot ancients, just give them hit's divived 10. Should arrive at reasobly similar result.
