personally I would get rid of the dual adsr and replace it with a smaller module - there are plenty of dual adsrs in 10hp or less - this would with the 4hp that is free allow enough space to add batumi> -- JimHowell1970

That's funny because I got my Intellijel Dual ADSR today :)
I like Maths for Inversion, Slew Limiting, as an Enevelope Follower, etc. but I wanted a full and classic Envelope Generator like in my normal Synthesizer (Novation Peak for example).

the other option would be to just get another case... which would probably be my solution

This would be the beginning of a very expensive Journey and I was successful to avoid that yet ;)
