cleiric warlock multiclass?

divine intervention for prayer of healing is downright overpowered. what if you were a warlock (or had team of warlocks) and gave everyone in your party a short rest? would cleiric10/warlock X work well?  

Prayer of Healing is, in general, a great use of Divine Intervention, though I don't know if using it to get a couple of spell slots back is worth the trouble of multiclassing into Warlock. The question would be what else you're getting out of the Warlock levels, and whether that's worth losing out on Cleric spellcasting progression.

I play war clieric and being able to do 6 steel wind strikes in a combat is fun. I just love having some warlock and just love the fiend features
