You mentioned you have Church Audio CA-14's earlier - are they omnis? If so I'd put the Telefunkens in the center and the Church omnis out wide. Two reasons: Low cost omnis tend to perform better than low cost directionals, and its easier to keep the larger/heavier mics in the middle.
I'd rather make configuration recommendations which I'm more certain of applying broadly, than specific mic recommendations which get muddied in personal preference, and I may not be aware of the most appropriate option. As I mentioned earlier, lavaliere omnis can work well. Maybe checkout whatever small inexpensive omnis Naiant or Church are offering these days. Larger (typical small diameter) phantom powered omnis work great as well of course, they just tend to be larger and heavier, thus more visually imposing and more challenging to support at wider spacings.
You might try searching TS for past threads with recommendations for omnis in your price range.
Edit- anyone else reading along have good specific recommendations?
