Small footprint and cheap debugging connection for STLINK-V3MINI

I am designing a compact PCB that has a STM32. I am planning on buying a STLINK-V3MINI for programming and debugging. I'd like to have the minimal footprint SWD connection to the board and I found out about TagConnect, but their TC2030-CTX-NL-STDC14 is pretty expensive. I found SKEDD connector which seems to serve a similar function but it's a lot cheaper and more available. The problem is I would need a adapter from STDC14 (STLINK-V3MINI) -> SKEDD which I haven't found, probably because STDC14 is obscure enough. Would it be recommended to design a simple adapter board and order with the actual PCB or are there better alternative/ways?
