it can be done, I've done it, but you need the 'contact ring' as well.
They are different between JDM & US models & can only be bought with the combination switches/indicator arms etc.
Cost:
JDM Momo wheel £511/$1000, airbag £402/$800, comb switch+ring £173/$340
US wheel £317/$600 (red/black only available), airbag £402/$800, comb switch+ring £?/$? still waiting for a price but probably the same as above.
UK prices + 17.5% tax.
Hope this helps even if to decide that it's cost prohibitive.
I swapped between VXs so didn't need to buy any parts.
