I’d say you basically have 2 options to remove the overlaps:
Simple - Go heavier on VWRL and reduce the geographic tilts (USA, EM, UK, JPN)
Cheap - Reduce VWRL and try and get equivalent exposure using smaller geography ETFs (although you are currently missing a few areas)
The simplest way to do the later would be VEVE+VFEM (Dev + EM), or you could do EM + N America + Europe + Asia ex + JPN or whatever other way you want to split it up.
