Jerry, you've certainly got great taste! (Your daughter, too.)
Those two sets are tremendous selections . . . and after watching you rip through Ripley's BION highs and Uncle Sam Home Defense high sets in record time, I'll forego warnings noting how "this set is impossible, etc etc etc".
There DO seem to be some Sea Raiders high cards out there, so it's gonna mainly be a matter of whether you'll be willing to pay the price. Judging from your energy displayed on Ripley/USHD, I'll put the under/over on you completing Sea Raiders 1-48 at 18 months!
But for MM&MS, I just don't think the cards are out there to assemble a set. Strays have been picked up and probably the majority of these are already within a few partial or completed sets. And for the strays you are able to locate, it'll also be a matter of whether you are willing to pay the price. Expect to start at $200 a card for even moderate condition specimens. Under/over on this set, if you truly build it (rather than buy a completed set)? Hmmm. 5 years?
I'm just playing here, so by all means go for what your heart tells you . . . and show us once again, what a determined man and his daughter can accomplish!!!
