I'd say go for it.

Oh, and if you dont have one already, go get a GOOD breaker bar too if you dont have access to an impact wrench too.
You used a combo wrench on your lug nuts? That would get old reaaallllyyy fast, not to mention only works if you have steelies. Try a socket next time

The only time I use a combination wrench larger than 20mm is for its box end as leverage for a smaller wrench

I would get ratcheting box end/combo wrenches in metric up to 19mm & standard up to 3/4" then 6 AND 12 point sockets up to 19mm+ and a 32mm & 36mm for Honda axle nuts. It's up to you what size standard sockets you want/need. I'd suggest having the sockets in both 3/8" and 1/2" drive too then you'll want some impact sockets as well. While you're at it might as well have a handful of bolt extractor sockets handy because there will be a time you will need them...the list goes on and on.
