Even with an arcjet, midcourse corrections wouldn't take anywhere near
that long. (Arcjets are not like ion engines, they have quite significant
thrust.) Do the numbers, please.
I can't imagine what kind of paperwork would be involved in purchasing a
chunk of plutonium for the nuclear battery...
Actually, none at all, because you can't. :-) There are no commercial
suppliers, period. The only organizations which have any are the US and
Russian governments, and quite apart from the question of whether they'd
ever be willing to sell a rather sensitive material to anyone, at present
they need all they've got for their own purposes, so they're not selling.
