Not recommended, as Rhinos are the weakest when it comes to dealing competent DPS compared to the other classes. If you wanted to go for pure INT, here are my pros and cons regarding that build.

90% INT, 10% DEX

Pros
-Able to use ranged weapons.
-Rhino Heal would be reliable for the party.
-Burst damage and DPS would be much better compared to the standard Str/Dex.

Cons
-Too squishy in mid to late game(Level 45-76).
-Useless in PvP as this makes you far squisher than it normally is.
-Only 2 skills are affected by Int; Holy Tempest and Heal.
-Skill Damage from your skills will be bad.
-Ranged combat desynchronizes with your skills as a Rhino's skills are meant to get close and personal.
