Yes Maths and veils first is a good start - then seriously take a look at links and kinks as the next 2 modules!
Veils will work perfectly for that application and for that matter the opposite (getting non-modular up to modular levels, as it has up to +20db gain)
It is unlikely that you will fry anything - most modules have input limiters which will clip the signal, to the range they specify, but will not fry at full modular levels, this generally applies to almost anything that you can stick a signal into - mixers and audio interfaces - you don't want that for these
But isn't that half the attraction of modular, that you can have a selection of whatever and mix and match?
Plaits has an lpg emulation, so the filter and vca are tied, you may not want this and want to just filter instead of use a vca, or the opposite, or have more control on the relationship between the filter and the vca (swap which is first, use different envelopes for the vca and the filter, etc)

Utility modules are the dull polish that makes the shiny modules actually shine!!!
