Went through the same thoughts myself recently - if you change the gearbox the actual engine swap is OK - quoted about $5-6K for parts only but it is ancilaries that hurt as well - radiator, intercooler, piping, fuel system, pumps, tank?, even getting the tacho to work. Overall when these are all taken into account costs were in the order of $8k without labour and without having to recondition anything.
LPG was the obvious alternative at about $3k for 72l gas and about $3.8K for 140 litre gas but then the cost of sill or other petrol tanks needed to be taken into account - the little 35-40l wheel arch tank is not realistically viable for long distance travel.
Solution was to sell the disco and will wait for a replacement (maybe a D3) in a year or two. The other is that if you add the cost of a conversion diesel plus what you get for the disco and add in a few more $$ you could get into a D2 Td5 with just over 100,000 km for around $18 - $19K. They are there if you are prepared to be patient.
