Primecoin as sidechain for peercoin

Could primecoin be used as a sidechain for peercoin? Primecoin is well suited to handling high volume transactions like bitcoin so i think it would be a good idea to sidechain to peercoin for this purpose. What do you think of this idea?

Does anybody have a opinion on this? come on primers!

Peercoin will have its own sidechains, Primecoin will also have its own sidechains. But I don’t think using Primecoin as one of Peercoin’s sidechains is suitable. Why?

[li]Sidechains can’t mint/mine;[/li]
[li]Sidechains use mainchain’s currency as common base currency.[/li][/ol]
