Can we be allowed to use "spared skillpoints" of one character to unlock other character's skills?

So when picking the skills for Wendy Wortox Walter I found that...I didn't have enough skillpoints to unlock all the skills I want for Wortox and Walter, and had more than enough skillpoints when it comes to Wendy...

Then I thought, "What if these spared points can be used to unlock skills for Wortox? I really want add the soul flute skill to my choice of skills", so... as title anyway.

Are you asking about earning them faster or exceeding 15? Because if you mean earning them faster I think they should have you unlock skillpoints in a fun, interesting, and engaging way instead of just afk idling, so that we aren't compelled to ask the question "Can I skip this boring crap?". If you mean exceeding 15 then that completely defeats the point of the skill tree since you would just go un-spend the points on all the characters you aren't currently playing at this moment so you'd be able to pick every single skill every time you play anyone.

The last time we saw this was in Hearthstone's visitor mechanic, which allows you to add cards from other classes to your deck

Sadly, just unlock them with a command if you don't want to progress naturally

I personally like playing each char to unlock all 15

It is something to do, I now unlocked naturally all skilltrees through megabasing and pubs and it is a fun experience that I recommend as a self imposed mini-game
