We recently transfered some IP space and ASNs from a company we 
acquired, and the process wasn't too difficult, once we got the 
appropriate internal folks involved to come up with the documents 
showing legal proof of the acquisition.

I don't think anyone expects the default maximum prefix length accepted 
to get longer than /24 any time soon.  The problem I see with prop-050 
is that it bypasses the APNIC minimum allocation length (usually /20 or 
/21, sometimes /22) and allows allocations to be carved up into /24's 
and sold.  If we see that actually happening, it will be much more 
difficult in the future to appropriately filter deaggregates (/24's, 
/23's, etc.) if the IPv4 routing table grows to the point that networks 
want to do so.
