Can I temporarily clean sankes by soaking in pbw or caustic?

[BrewVerymore]

I have recently started kegging with Sankes and am currently waiting on my pump to complete my keg washing build. Unfortunately, the pump wont arrive for another couple weeks and I have some beer I want to keg right now and a bunch of dirty kegs.

I was wondering if I'd be ok with just filling the kegs up with caustic or pbw and letting it soak overnight or what would be the recommended method of cleaning by shaking/soaking.

THanks very much!
