Hmm I had forgetten you had a TI - that changes thing *alot* - given where you are - you have a TI, Nova and a JP? Thinking of Radias now, maybe v-synth later?
This makes everything very easy IMHO if you have to ditch something - I would ditch the nova now - get a radias and later ditch the JP and get a v-synth - or the other way around if you are really attached to the nova.
The TI should allready be covering most of the nova space - except bass maybe - the radias can easily hold that space where the TI cant, but there is quite a character difference - but maybe time for a new sound anyway?
And yes - the radias *is* very groovebox like in some ways - and thats a huge strength for it - having the SEQ mods available make it very useful for background textures, airy/twinkly bits of digital pads etc - it layers great over a TI - radias for impact and air, TI for body and richness.
I echo HCs comment tho - keep the lot
