Not very convincing, Nadie.
Okay, so you aren't a convert but you were a bad Catholic who became presumably a good Catholic. It's kind of the same. I know someone like that who considers themselves a convert.
Anyway, it's irrational to make a blanket statement that you wouldn't let a convert marry your daughter, some of them may make better Catholics than you.
I usually don't like the term "bad Catholic," the way that it is used today assumes that one can be habitual bad and yet remain Catholic, which is false. It should generally be replaced with either with ex-Catholic, lapsed Catholic, or faithless Catholic. Nadie may not be a "convert" but he is then a revert, and thus is no different than most converts.
