Crusher Creel, the Absorbing Man, has the ability to absorb type of material be it gas, liquid, solid or energy.
According to Wikipedia (not the best source) his powers and abilities states:
Creel's overall power increases in direct proportion to the strength of the material absorbed. There is almost no limit to what Creel can absorb, as he has absorbed the properties of bronze;cocaine; Odin's Cosmic Bolt and later cyclonic storm; diamond; glass; light; rock, silk, soil; spikes; steel; Thor's uru hammer Mjolnir; water; and even the properties of Asgard itself.
As it states that the Absorbing Man absorbed Odin's Cosmic Bolt which has been shown strong enough to cause ripples through-out all the planes of reality.
Would it be plausible in theory for him to be able to absorb a portion of the Phoenix Force?
