I suspect that if "spontaneity" is a requirement, then this idea is doomed!
TBH, you can only use a SIB in the very best of weather - especially if the "crew" are rookies. Investing in an expensive system to launch a SIB is, IMO, a complete waste of time and money - like spending €5000 on a machine that opens the cupboard, grabs a tin and opens it for you when you suddenly feel hungry but disinclined to stand up - impressive but pointless!
As I see it, you have two choices here:
1. Buy a lightweight SIB and engine AND an automatic inflation pump. Make a decent holdall bag for the SIB and get a very good balloon wheeled trolley for the engine/holdall. Unpack on the beach and launch there each time. When you get bored with short local trips to the same places, sell the SIB and engine and use the trolley for something else. A small SIB full of adults is a fairly horrible experience.
2. Buy a smallish RIB - c.5-5.5m and moor it just off shore. When you're not using the house, recover and store it at the nearest marina/boatyard.
