I think you will need some malted wheat in there. The DP of continental pils is not real high and I don't know how well it would convert 50% adjunct. The DP of American malted wheat is as high as six row.
I used 40% uncooked, unmalted raw hard red wheat with American two row once. It had a thin mouthfeel, not much wheat flavor and it cleared. Malted wheat has more flavor.
Here is is.
