Changing rims for TOCA

[Roka]

Hi,

Does anyone know if it's possible to change comfort rims of TOCA Custom Deluxe congas to
traditional ones of TOCA Traditonal Series or Sheila E. Custom Wood Congas ?
The head measurements are the same, but I'm not sure if those drums have the same shell.
I noticed that there aren't so much discussions about TOCA products, but maybe anyone had any expierence with those ?
