I completely understand. It requires having friends that are into the game and willing to learn and then it requires to commitment to show up every week (or whatever timeline you set) and play. I would encourage you to play online (I would of recommended /r/lfg on Reddit to find a group but I assume we're here for a reason [If anything you can get on reddit just to find a group and dip]), either finding a group online or convincing friends you already have to play.
If not, there's usually enough buzz of DnD in the our modern day society that most younger people have probably heard about it and are curious. Realistically, everything you need to play is online and free. The Basic Rules are free and it is not hard to find the other books you want online for free (Not sure what Lemmy's rules are about piracy but if you want to talk send me a message).
At the end of the day, it's more about telling a story than anything else and a lot of people can get behind that. Now if you are simply too busy I understand, but I highly recommend everyone to try it.
Also I love your character idea. It is honestly so simple but it has so much potential and honestly kind of bad-ass.
I don't know how you or your table feels about third party stuff but Indestructoboy has a a Runekeeper for 5e that is heavily influenced by the 4e one (I've never played 4e so I can't verify this myself.) It looks very awesome and you might like it. It is not free but you can download a preview of the whole thing for free from the dmsguild site (so basically free).
Here's a Youtube Video where Indestructoboy goes over it.
