I\'ve rested up a bit and am starting work on some 1.5m parts. The total set, for the first few releases should be: 4 liquid engines (1m and 2m) 7 fuel tanks (1m, 1.5m, 2m diameter with 1.5m high and 3m high options. also included is a bare and compact 1m tank) 3 command pods (one is 0.5m) a slew of adapters (0.5m to 1m, 1m to 1.5m, 1.5m to 2m, maybe some reverse ones or a 1m to 2m coupler) modular engine and payload shroud system (in all sizes, with optional decoupler pieces) RCS quad and fuel tank service module (1m only, possibly a 1m to 1.5m adapter service module in the future) 2 killrot modules (0.5m, 1m) 3 parachutes (0.5m, 0.5m stackable, 1m) 4 decouplers (0.5m, 1m, 1.5m, 2m, also serves as a mounting point for the engine/payload shrouds) stage separation retrorocket heat shield (hopefully physicsless) 2 SRBs (0.5m and 1m) Mother of god, what am I getting myself into? Also, I decided on a fuel consumption scheme. The fuel to weight ratio for tanks is very close to that of vanilla, 200 fuel to 1 mass. That way, you can hopefully use the relatively high-consumption (but realistic) SE engines in conjunction with other packs. And vice-versa, but I do not endorse that in any way.
