The game uses Magic Points, or in this case Focus Points. The idea of combining the same spell was because they had "uses" instead Magic Points.

If you want to use slightly less FP then equip the Dusk Crown Ring. This is mostly a late game Ring with high Vigor, in the 18-28 range or above if not going for a level cap.

If they did have stacking spells, it wouldn't really make much use because there are better versions of certain spells...

Soul Dregs, then Great Soul Dreg. Soul Spear, Crystal Soul Spear.

Soul Arrow, Great Soul Arrow. Comubustion became Pyromancy Flame Weapon Art, and Great Combustion is a spell on its own.

Though I think the WA for the pyro glove can be very useless, where Parting Flames Combustion bonus seems to be a better upgrade.
