Padcaster Fluid Head Tripod/Monopod

does bh sell a tripod that's basically the same functionality as the padcaster ( BH #THPCTRIPODG2 ), but can handle 20lbs? Specifically, 71" height, with a more narrow footprint like the padcaster. I shoot indoors in cramped spaces, so appleboxes is a non starter and would slow my workflow dramatically. Also the boom-able center column is a must, since I can set it in the middle and save adjusting all 3 legs, instead just adjusting the locking center column. For same reason, prefer flip lock legs, saves time. The leveling half base (the orange part of the padcaster on the center column, bottom half of the fluid head) is exceptionally useful for leveling, and the fluid head / flat video head design is most reliable (contrasting the sirui BH #SISUW2204K20 ballhead, which I wouldn't feel comfortable putting my cage/camera/monitor/98wh batterry on) budget is $300-500. is the best route to piece this together? would need the 71" height, the fluid head base (once again, not for recording camera movement, but for video head platform reliability, to use w/ a cage/rails/98wh battery/monitor system). and the center column w a hook to add a sandbag.

Is this compatible with blackmagic designs 4k pro g2 ?
