[Suggestion] A way to make Hanamura more common without limiting map pool

So I remember back when machines of war came out that Blizzard stated there was no way to make a new map more likely to be played than the old ones. Now I don't know about you but 6 maps is awfully small and gets stale quick, but how do we fix this without making it less likely to get Hanamura?

My suggestion is fairly simple. Instead of increasing the the chance of getting hanamura, what if Blizzard put 2 hanamura maps in rotation. To differentiate one might be the same as it is now, while the other has 8 core health as opposed to 7. This way it makes it twice as likely to play hanamura while simultaneously giving the player base a way to compare how the different core healths will play out. With this they could also raise the map pool to 8 or even 9 which would mean hanamura would have a 1/4 or 1/5 chance to be played, while still having good map diversity otherwise.

What do you guys think? Would that be too much hanamura or is the simple 6 maps better as it is now? To me it is a great combo to play more of the new map while testing slight variations

TLDR

Put in 2 hanamura maps in rotation, 1 with 7 core health and one with 8. This gives a way of playtesting while allowing for a map pool of 8 or 9 without making hanamura too uncommon.

Whew that turned out longer than I thought, thanks for reading :D
