Might be cheaper, but i don't see how increasing the top players main accounts at the cost of SGC's main account (which he will have already taken HEAVY losses due to ascending) actually helps him. Honestly it takes a little time to get going on ascended anyway so IMO he'd be better off by far to spend LF on charisma and start buying fleets with earnt DMU. With the multiplier his charisma would add then it won't be long before he's making plenty of planets.
Converting LF into DMU is not that good, DMU can only be used to build stats and buy fleets, LF can be used for so much more. Hell, in the longer run it would be more cost effective to use the LF he would have converted into DMU to buy up a load of Energy channelling, then start converting newly generated Cache into DMU.
You could get to 100k fleets by converting your initial LF, but if you spend that LF on personal stats and Energy channelling then you would have invested in a steady supply of earnt LF as well as making it pretty much impossible to be descended. What's the point in having 500 Charisma and 100k fleets if you are descended and can't access the game for 2 weeks
