Is there a mod for changing tank fuel types ON ORBIT

[proteasome]

Anyone know of a mod that will allow me to change a tank on an existing orbiting craft from LF to LF+Ox? Not in the VAB/SPH, but in a craft that's already been launched? (I don't want to send a new drill rig to jool b/c I can't change one of the tanks to include oxidizer.) Any advice appreciated. thx.

I can think of several - but all of them would need to be installed before you launched the craft.  If you launch the craft first, I believe the module that applies the mod's effects won't get applied to the part, and you can't use it's features.
