I would say skipping cleric C2 is rather problematic for any cleric build. The truth is, cleric c2 heals more than double what a cleric c1 can heal. This is because not only heal lv 10 doubles the amount of squares on the floor, but it also makes each square heal slightly better.
If you’re going full STR or even half STR half INT, I would say certainly don’t skip cleric c2. STR doesn’t increase your healing power, so only having Heal lv 5 on a STR (or half STR) build will make your support capability extremely weak (even to heal just yourself!). You’re a cleric and you want at the very least to be able to heal yourself and not have to rely on HP pots.
Being a full SPR or full INT build, you can pick only cleric c1, but be aware that it’ll only be enough to heal yourself only. It’s a rather selfish option, in my opinion, because most players expect clerics to at least heal their party members when playing with one.
Taking two circles of krivis is not really giving you a great amount of extra damage. Zaibas isn’t bad if you are a full INT build, but I wouldn’t recommend going full INT on that build since you’d only have Zaibas + Carnivory dealing magical damage (with divine stigma being used mostly to buff Zaibas dmg). Between Zaibas + Carnivory full INT and God Smash + Demolition full STR, I would pick the latter (overall better skill factor and more burst dps).
If you really want to go full INT, it’s better to scratch the whole build and remake it thinking on magic-focused classes. Paladin 2 is getting zero benefit from a INT build. So maybe you can turn that into Sadhu 2 or even Krivis 3 Cleric 2. You may also want to rethink Inquisitor at the end (maybe switch it with Taoist?).
Hybrid builds with both physical and magical skills can work, but they require high enough trans weapons that make STR / INT stats meaningless. If you have the option to choose between two builds, one that requires a lot of investment to be decent, and another that doesn’t require as much investment, why would you choose the first?
It all depends on what you really want. If you 100% don’t care about your party and want to be a solo player, Cleric 1 isn’t a bad option. If you want to party occasionally, I wouldn’t recommend ditching cleric 2.
Carve atk has too low skill factor and always hit only one target. It’s not really good enough even when using on Breaking Wheel.
