There's no Intelligence minimum to cast spells, nor do more intelligent wizards get more spells.
Not true ... The more intelligent your Wizard is, the more spells he can prepare.
But even if that would be true your hit change is calculated as your roll + proficiency bonus + (and this is the important part) your INTELLIGENCE modifier (for Wizard)
With Shocking Grasp you do 1d8 ... just as the staff do ... I know that staff with 14Str gives you +2 to that damage and hit ... Shocking Grasp gives you advantage on hit against targets in metalic armor, strips your oponent of reaction for that round, give double damage if your oponent is wet (funny, this condition can easily bring certain staff), and you would still get all the other benefits (including hit bonus, but not damage bonus) from your class "main stat" (wich isnt named like this without reason )
I mean ... is that really a competition?

Not sure about viable ... its certainly possible.
Question is what stat do you sacrifice to get your 14Str? - Dexterity, that gives you better AC, wich is quite useable for squishy Wizards? - Constitution, that gives you better HP, wich is quite useable for squishy Wizards? - Intelligence, that affects basicaly everything that conciders you class?
