I know exactly what you mean Doug. It was just an idea without me knowing much about the architecture of the lander itself. What was leading in the idea, is that an RTG is self sustaining: it doesn't need anything except a place (which is not available considering your reply) and a galvanic line to the bus (which shouldn't be a problem). The money however is always a "problem".
I'll forget about it.
Marcel:
Not just the money, but the fissile material - believe it or not, fuel for RTGs is in short supply, and the New Horizons Pluto (and beyond!) vehicle was under quite a lot of pressure at one point due to the inability to get the thing fully topped off...
Interestingly, there are radionucleide heaters in the MER rovers, and even aboard Pathfinder - and there were tons of the things aboard Mars-96, now spread over the Andes... ...well, not actually tons, but it does give one pause for thought when the 'no-nukes' brigade pipe up!
