Repitching onto yeast cake at low temperature?

Hello fellow Beer Nerds

Apologies if this question has come up before, but....

I am using the excellent WLP029 Kolsch yeast again, and will first be making a pale 'fruity' kolsch, then pouring new wort on the yeast cake to make a more malty, 'clean' Altbier.

I am keen to avoid the hassle and potential contamination of yeast washing. However, I was planning to drop the first Kolsch to a lager temp (~2℃) in my fermentation fridge, and would then like to dump 16℃ wort on top of the cake, for the 2nd beer.

My question is, would the change from 2 to 16℃ shock the yeast, and if so should I warm it up prior to repitching, or would this impair the effects of prior lagering (flocculation, smoothness, etc)?

Any input greatly appreciated,
Pete.

Thanks Trout.
Yes, that's exactly what I was asking. Good advice, I will cold crash, pitch low, then warm up.
Much appreciated,
N.O.
