Tavor SAR - HK style charging handle?

[Inkognito]

I understand the Tavor 7 has a nifty little feature that I really like; the ability to push the charge handle up and lock it open. Would there be any way to modify a Tavor SAR to have such a feature? That would really add a lot to the SAR in my opinion. I prefer the SAR over the X95 in almost every way but I really want this option.
