Am I the only one who thinks CA-14s would still eb an upgrade to those OHM's
I say get CA14[Cards/Omnis] and a 9100/9200 CA Preamp and be done with it 
I don't think it can beat the 4.7k modded MM-HLSO's, but that's a matter of taste.

You (Dominik) will be able to listen to alot of samples over at archive.org, dime-a-dozen, zomb tracker... Just do a search by mic model and let your ears be pleased.

You first asked for a budget rig, but then talked about getting some DPAs.
My advice : take the DPAs if you have the $$$.
Otherwise, if you do 90% stack taping take the 4.7k modded MM-HLSO's that someone is selling in the yard sale for 150$. Amazing bang for the bucks.
If you had to pay 280$ for a brand new MM-HLSO's pair + ~20$ for the 4.7k mod (+ postage), I would have told you to get the CA-14(o).
You'll always need to power the mics so save some money for either a battery-box (cheap) or a Church Audio 9100/9200 preamp.
I personnaly improved my sound by keeping the same mics but switching from a simple battery-box to a CA preamp.
One last note : ask Chris Church for a built-in switchable bass roll-off filter if you order his preamp. You'll need this when using omnis
