XMWX world ex US -balancing

Hi everybody

Have anybody got any ideas on balancing out my index fund trackers and an ETF?

I have got:
50% L&G US Index C Accumulation : ISIN GB00BG0QPL51
50% HSBC FTSE All-World Index C Accumulation : ISIN GB00BMJJJF91

I am considering adding XMWX into this, or swapping a tracker out with XMWX

The XMWX is EU developed 45%, Japan 19%, UK 12%, NorthAmerica 12%, and Australasia 6%. ( % are rounded ). I presume North America is Canada and Mexico.

The HSBC all world is around 60% US, and 40% developed EU, China, JP, UK, Canada.

All of these index funds and ETF have got low running costs.

What is a good way to do this?

Thx
