Generally speaking yeah. Considering you already have fins. Wettie for travel is generally a 1 or 3mm depending on what you're doing.

For gear, don't forget to factor in the occy and inflator hose or an air2.

If you aren't interested in going to DM or diving multiple times every weekend over summer, you can get a lighter duty BCD which will save you a few kg. I love my oceanic probe but its too heavy.
