No. Workhorse IR's are in Line 6's ".hir" file format, which is a proprietary encryption only readable by the Line 6 products built to accept this file type. This currently includes the "Helix Core" group: Helix hardware and software, HX hardware, and POD Go.
No. These libraries will never be made available in wave audio (.wav) format, and are currently only available through the Line 6 Marketplace web store.

(click to enlarge)The specifics are considered proprietary, and the relevant disclosable information can be found in the "IR Voicings" section of the PDF documentation included with the purchased library from the Line 6 Marketplace.
The price point per library is dependent on the amount of content provided. $19.99 priced libraries have one "speaker option" section, where $29.99 priced libraries have three. Thereby the higher priced libraries have 300% more content for an only 50% increase in price.
No, and for several reasons:
The maximum amount of IR's that can mixed within Helix and HX patches via split/parallel impulse response blocks is 2, to which the Multi-Speaker Mixdown files are comprised of 4 independently leveled components.
All of the files are mixed by ear, and all end up leveled at different values as a result. Mixing the "X" files will not garner the same sound.
The IR's are mixed in ways using procedures and tools not possible outside of OwnHammer development, again resulting in a unique sound.
Using multiple impulse response blocks results in their resolution halving to 1024 samples, where Multi-Speaker Mixdown files only use 1 block and stand at a resolution of the full 2048 samples.
Units like Pod GO do not allow for multiple cabinet blocks, thus any kind of mixing is not possible.
As can be observed, the results the Multi-Speaker Mixdown libraries achieve cannot be recreated, thus their necessity as separate sales items.
