Paper variants?
No.
Try to play MoW:AS2 game for your wishes.

Men of War Assault Squad 2 models.

I have plans to add real tank like early war Type 95 heavy.

Do not have any plans for paper tanks like Ho-Ri.
Try to play MACE that will have prototypes/paper tanks.

Use in AT role real 75mm Type 88 AA gun that have mach better penetration than experimental 57mm Type 2 AT gun.

MoW:AS2 game does not have such power and cheap AT weapon as 75mm Type 88 and adds experimental 57mm Type 2 AT gun.

I have already take those tanks at MoWAS 2 and it take me less than one hour to get them working at Ostfront. Some of your Japanese models even AI shoot like machine guns.

I don't have such skill to use 3DMax and make working PaK 57 model at Ostfront.
