How about a base model s300 57mm comp and a 16cm wg housing as the small turbo and 74mm holset with either a 241 housing or a 1.10 housing? I know the 241 is about a 17cm housing but Im not sure of the 1.10, Im guessing its bigger? I know this probably isnt the best setup but I can get both turbos and I think it would be fun to try.

 

it should spool pretty good but it will be limited on the top end.
