KEF Reference 5 aftermarket plinths, base, or feet options?

Can anyone recommend feet/bases for the KEF Reference 5?  I would love to not spend a fortune as I wait for new plinths from KEF (out of stock for a while).  

Note, if you're not familiar with these speakers you can't just put feet on them because the screw holes underneath are NOT way out at the corners.. They're more centered.. So I cannot just throw on some ISOAcoustics GAIA feet.

Thoughts?
