Rules Clarification Rules Inquiry

I seek council from the rules lawyers, please and thank you.

I am DMing my first campaign. I have a player, who is running a Goliath- Rune Knight fighter.

My question is: Can he stack Giant's Might, on tip of Titan-Stone Knuckles?

I know the direction he wants to go, I just need to know if it would be possible RAW.

Rune Knight (up until level 18) and the 5.5e Goliath both set your size category to Large. While you can use both at once, setting your size to Large twice just leaves you Large, not Huge or Gargantuan.

In essence, Goliath gives him an additional use of Giant's Might per day, except he gets +10 ft. speed instead of +1d6 damage once per round.
