The origin and current evolutionary path of massive low surface brightness (mLSB) galaxies remain challenging, unresolved problems in astronomy. Recent results from GALEX and HST suggest that mLSB galaxies may be analogues of the extended UV-disk (XUV-disk) galaxy population operating on an extreme scale, perhaps driven by heightened gas accretion from the intergalactic medium or neighboring galaxies. If so, they would represent a galaxy population undergoing a secondary, delayed stage of [disk] formation regardless of their prior history (red/dead elliptical or star-forming spiral). We have used GALEX to identify a sample of UV-bright mLSB disks caught forming around otherwise normal early-type (E and S0) hosts, which appear to support such a scenario. We will present analysis of two example objects, using UV imaging in conjunction with VLA/WSRT HI maps and ancillary optical data. These currently-forming LSB galaxies each have conspicuous spiral structure in their huge, massive gas disks. Evidence for accretion of the gas disk is also seen, in the form of disturbed HI distributions.
