Second regulator

Hi all, been a while since my last post and hope all is well with all :)
Just wondering if any Uragan shooters have added a Bottle Reg as a primary reg to take some pressure off what would now be the secondary reg (original reg ).
Have seen this on other pcp's but not the Uragan. I think that a moderator may be a bit of an issue due to the bottle being brought forward and the bottle guard may be a bit of an issue .

Thanks
