In theory, yes. However, unless you already have a Eurorack rig, this seems sort of inefficient. You're talking about $519 for the modules alone, plus whatever case/power you'd have to get if you don't already have that on hand. And then, you'd only have two channels (and no velocity...the Bloom doesn't transmit that). Plus, both of those Elektron boxes already have sequencing onboard.
If the idea here is to employ a master sequencer to control the Elektrons, or to inject random variables into the behavior of those boxes, it would seem to me to make more sense to employ a standalone device such as a Squarp Pyramid (if you don't have a Eurorack rig already) or a Squarp Hermod (if you do). The Hermod has MIDI (no need for the Doepfer module), does transmit velocity and aftertouch (bonus), has ample randomization and parameter stacking for days. And the Pyramid is basically a beefier Hermod in its own self-contained case. Plus the Hermod actually comes in at $20 less than the Qu-bit/Doepfer pair and gives you eight tracks whereas the original idea only offered two.
