Alternative to vancian casting

I got this idea from the sovereign stone rpg. Instead of fire and forget or mp based spells, try seige checks. In order to cast a spell the magic user musr succeed at a seige check of 12+spell level. Success allows them to cast the spell, but failure means they must try again next round. As a perk, what ever their total is from the seige check can be carried over to the next round and added to the next seige check. This means it will take about 2 rounds to cast a spell, but since the spell is available to be used multiple times, the trade off is worth it.
Additionally, at the beginning of each round that a magic user is trying to cast a spell held over from the previous round, they must make a saving throw. Failure results in sustaining 1d4 dmg.
Example, a wizard is casting magic missile. A level one spell. To cast it, the wizard must succeed at a seige check.12 for CB and 1 ( the spell's level) for the CL. the die is cast: 5 (ouch), add casting attribute (int for wizards) +2 and level of pc (he's level 1). A total of 8. Darn. No spell this round, but the wizard may try again next round. At the start of the wizard's next turn they continue to cast. However, magic is taxing, the wizard must make a saving theow (I was thinking CON or WILL) CB of 12/18 and a CL of X (X=number of rounds, beyond the first, spent casting. In this case 1). The wizard succeeds (failure means taking 1d4 dmg). Now, the 8 from last round remains in play. The wizard rolls again... Another 5, today is not his lucky day. Oh well, 5+2+1= another 8. Take the 8 from last round and combine it with the 8 from this round and, viola! The wizard has beat the seige check and successfully cast magic missile.
The idea is to allow magic users to use their spells over and over again, but not allow them to fire magic missiles willy nilly. This system does have some flaws, IE a cleric who casts cure light wounds all day long outside combat.
