easy job - could either reduce the number of holes in the drilled disc - OR -
print the disc element on transfer (like the AR10 sheep or GM4 midgie).. The only issue which springs to mind with the latter, is that the Flex used for the lettering has a nice msatin finish, but the printed transfers take on a matt finish once pressed so might look like it's been dropped in place afterwards.
We could happily do a test pressing and supply to dizzee/AR organisers to see if they're happy (and post pics on here but won't be as obvious/clear). It won't be screamingly obvious, but aesthetically there may be one or two people who deem the over all finished garment not to be of the best quality, simply because the transfer might look a little like it's been thrown together.
For those of you who've got your AR shirts from last year (sheep logo) have a look at the difference between the flex and printed transfer
