GarfieldModular and Ronin1973, thanks ever so much for your help! I’ll take a good look at your recommendations. You’ve addressed the two things I knew were either slightly off (for some reason utility modules have been hard for me to get my head around) or not taken into consideration enough (modulation). I’ll be back... Thanks again!
Edit: Sticking with the Erica eg/lfo for now in my projected build as I have some space issues. Will keep an eye on the Intellijel Dual ADSR module.
