I am now assuming you got indexed shifting and you have no way to turn the indexing off to get friction
A different number of gears would not be a problem, you'd just adjust limit screws so the chain can not fall off if needed.
Different spacing is a problem with indexed shifting because your shifter has a fixed amount of cable pull per gear, this moves the deraileur a fixed amount.

Is a carbon frame of mine. It never rubbed but all the shit (road bike) that gets sucked through there can eventually wear the paint. This exposes the composite. The composite we see today is often designed to be relatively dry aka designed to have a matrix deficit. As such I am worried it could draw water when exposed but I have no source nor data on this actually being the case.
Why do you want to run 28s? Is it just what you had on hand?
