They can and they will find a way to bend the rules. Actually, Nasu will find this way. From what I understand, Moon Cancer is basically any programs that can hijack the Moon Cell to various degrees.

In that case, as Valeth pointed out, Archimedes and Kiara can be a Moon Cancer (if they are summoned as programs and not spiritual bodies), any Regalia holders can potentially be classified under Moon Cancer too (making way for MoonCrunched Tamamo/Nero), even Moon Altera could be one. And yes, a program-like Liz could be such a Servant depending on her actions.

We might see a lot more Mooncancers in the future, but they most likely are going to have extreme circumstances behind them and, in that case, will always be limited by various technicalities.

...Unless they change what is a Mooncancer in FGO universe, opening a lot more possibilities.
