Actually I think all of those extra pins are for signals and not for
power, so the only thing you would lose with a 'shorter' slot is
performance.

Another thing you could (at least in theory) do is the remove the
rearmost bit of plastic from the slot on the motherboard so a longer
card could fit.   I do know that there exist some motherboards with
'open' rear-ends of PCI-E x4 slots precisley to make it possible put a
longer card there.  (Assuming it does not interfere with any other
components on the motherboard anyway.)

The general rule with PCI-E is that if you can physically fit a card
into a slot it should work. (Althouh there do of course exist
exceptions with some cards and motherboards.)
