Fiat panda 4x4 and LPG conversion?

[Fiat 4x4]

Hi everyone . . .
I'm very new to the fiat 4x4s but thinking of buying one and converting it to LPG . . . .
I'm wondering if anyone knows if the wheel well where the space saver is kept is big enough to house the tank?
I'm trying desperately to find a small 4x4 that has a wheel well so the valuable boot space isnt taken up by a big tubular tank . . . .
Also . . . . does anyone know if the engines could cope with the conversion?

Thanks in advance for any advice,
Charlotte

I'm sure there economical enough without LPG, when they say you have to wait years for LPG to start being a saver, it will be in the case of a panda.
