The dividend in the pound is that returnable to creditors, not what is divided up between creditors and IP. Insolvency practitioners do charge at differing rates - but in general creditors keep their eye on what is being charged and exercise their own scales of reasonableness.
This poster could offer a higher dividend by increasing the amount to be eventually raised from the equity, but then gambles upon eventual affordability and the ability to re-mortgage to raise sufficient funds.
It may also be possible to extend the term of the arrangement, to also provide a higher return, as in my experience HSBC will not budge from the 40p ruling never mind who the IP is!
