Maybe you hire someone who has the free time to haul them out there and you catch a cheap flight close to there. Vegas tends to have deals, they presume you are staying in that area...
You could hook up with the "driver/transport" and you pay the gas and meals and inexpensive hotels for a 4 day trip to get there, if you hook up in Vegas quickly. Then you can spend a long weekend or more in LaLa-land. Play tourist if you haven't been there and take in a bike show or classic auction and enter the bikes to sell...preferably you sell them yourself...
Some people would like the trip...but we are fast approaching weather that makes the trip more of a challenge. So, you would need to do it soon.
The transporter would use equipment you provide and they have insurance and a great driving record.
I know someone who could do what I've described. If you are willing to give it a spin.
Gas prices are cheaper so, it would be a few hundred cheaper to do it. You would need the flexibility to allow them the freedom to spend a week on their dime, resting and enjoying the west coast...
Heck, meet up with a few Westerly coaster (SOHC/4 owners) and have a parting ride...Maybe with Godzilla if he's doing anymore touring. Mooshie usually kicks off the trip but, I'm not sure where Zilla is these days or if interest has died for that activity.
Commercial movers will charge you minimum of $700-$1200 to move a bike from coast to coast and it will be packed in their equipment like a sardine.
Ballparking...
BUT, movers pretty much take the winter off because of the increased liability and risks involved with the weather problems in Winter, even on most southern routes you risk ice and snow most years...especially in late Jan-Feb.

P.S. They could fit in a large full size van with the mirrors off. Could even rent a van if you don't have access to one, pull the seats and strap them down and cover them in a black plastic so they can't be seen and outline is not distinguishable. Maybe fake box around them both. Use seat anchor bolts or seatbelt anchors to piggy back the D-ring to hook your ratcheting straps... pull the mirrors...
