that would be great! bonus if it could be scene or parameter locked. 
compression and spacializer after delay or reverb without a neighbor track would be nice.
just being able to only load one of the time effects, but in either slot 1 or 2 would be help, but i do like the idea of switches.
parallel would get funky with filters! as well as comb filters you could play two resonant filters in a track too.
