If you write a Linux wrapper that sets the capabilities appropriately
and then execs Wine with the execve() function Wine will inherit the
capabilities, but can only pass them to your process if it uses execve()
to launch Windows programs. 

If none of the Wine devs[*] supply the answer you'd best look at its
source to see what it does and raise a bug if it doesn't use execve() to
launch Windows programs.

[*] disclaimer: I am not a wine dev and haven't seen its source. Since
Wine runs the apps I need I'm not planning to read its source anytime
