Swap From Trailer to Stands

Anyone have insight to using a long - 10', 4x4, or (2) 4x4's under the bow to quickly swap the Scot from trailer to stands ?
The bottle-jack jockey is a 45 minute hassle.
I'd love to get (1-2) 4x4's long enough to clear the trailer wheels - use two bottle jacks on top of cinder blocks with the 4x4('s) on top of the jacks - rest the hull by the transom on boat stands, and bottle jack the bow up in one shot - and slide the trailer out.  5 minutes !  Then boat stands in the front.
Obvious concern is the weight snapping the 4x4 although I doubt (2) 4x4's side by side would break.
Not looking for a dangerous situation, just a safe, faster one.  Anyone do this ?

Just curious, did you try this?  I have always done most work on the trailer, and if I need to do bottom work, I usually "launch" the boat off the trailer on to the grass with a tarp under it.
I have also done quick bottom work by lifting the boat with the hoist at a club.
What was the goal of putting it on the stands?

I have not tried it yet but will do so in the Spring.  Every other year I transfer from trailer to stands to get a full coat of antifouling on.  I've wanted to try the (2) 4x4's for awhile.  'Should' work.  Also, I think I might try to shim my trunk as it's a 1965 hull and all original 'down there'.  
There's always something to do - need to R/R my through seat copper drain tube - I've done (at least (2) of the others in the past.  I try to keep my ole girl, yare...
