Don't wanna be that guy who is skeptical and hopeless with full of negativity but there is really no point into creating this generator. If you wanted to test your skills, then great! But if you think that there could be made a project out of this, then no, don't hope that!

1. You suggest to use unique details. Okay, but then what's the point? If I have to type unique details, I'll just download Electrum and generate my wallet via Electrum.
2. You have to keep in mind that 99% of users will probably enter the information that they have already entered on different platforms. So, 99% of people will experience hacks and loss because this generator generates address according to what I type. If I fill the fields, save information and refill it again, I receive exactly the same seeds, entrophy, etc.
3. The way Electrum generates seed phrases is safe enough to never worry about getting your wallet randomly hacked.
