Trying to re-create Vanguard Global All Cap on Invest Engine

I've recently binned Vanguard due to their fees and I'm moving to Invest Engine. I know there's no equivalent to VAFTGAG on other platforms but after some research, I've gone with Vanguard FTSE All‑World (VWRP).

I know this includes only mid and large companies, so to compensate I'm looking at some small cap options like iShares MSCI World Small Cap (WLDS) or Fidelity Emerging Markets Quality Income (FEMQ) - are these more or less the same? Or is there another I should look at?

I'm also thinking of splitting it 90% VWRP and 10% Small cap. Unless I've got this all wrong, would this be the best way to replicate VAFTGAG?
