Only ten basses, duh? Should be easy...
Have you seen the movie The Prestige? Spoilers: There's a machine designed by no other than Nicola Tesla that gets you an exact copy of whatever you put inside. So, I would put in that machine the folloging basses:
1. Juan Alderete's Fender fretless PJ bass
2. Ben Kenney's Lakland "Baby-J" 44-60 short scale
3. Jaco's Bass of Doom, but I'll have it refinished in daphne blue, with matching headstock and a white pickguard. I know, heressy

4. John Paul Jones' Fender J
5. Flea's Modulus. THE one with the stickers, yah know
Then, I'll get a
6. Fender custom shop Sean Hurley P in 3 tone sunburst with an anodized gold pickguard
7. Mike Lull JAXT4 Jeff Ament Signature
8. Wall MKII
9. US Lakland 55-94 in black & maple
Finally, even if it's not exactly an electric bass, this one also goes into Tesla's cloning machine:
10. Scott LaFaro's Double Bass drool
I guess I'm going to need a bigger flat
