Would this Switcheroo Strategy work?

So I’ve been thinking of making a Doubles team, and I think I came up with a good strategy for Lopunny and Furfrou.

Furfrou@Whatever item (turns out mega stones can’t be switched )Nature: JollyAbility: Fur CoatMoves:Cotton GuardZen HeadbuttWild ChargeHeadbutt

Lopunny@Assault VestNature: AdamantAbility: KlutzMoves:SwitcherooDrain PunchDizzy PunchIce Punch

So here’s what I’d do:

Furfrou uses Cotton Guard, and Loppuny uses Switcheroo to switch the Assault Vest with the item (thanks to Klutz, Lopunny can still use Switcheroo despite holding the Assault Vest). Then I can have Furfrou tank everything like a boss thanks to the boost in both of its defenses.

One last thing: if this could work, how many speed EVS would I have to give Lopunny in order for Furfrou to out speed for sure?

EDIT: Turns out mega stones cannot be switched, so I changed it up a little.

Tried it on PS!, as I couldn’t get it just from Bulbapedia.

This is what they showed me:

Although, itwasillegal when I tried to make it learn. I just didn’t pay attention.

Besides, it is a waste anyway, since Lopunny is still too frail. You’re better off with the regular sets.

The check box to mega evolve Lopunny just isn’t there.

Mega stones can’t be tricked. On the other hand, setting up is kinda redundant in doubles.

Hope this helps!
