sorry to rain on your parade , but what exactly has this to do with road racing  or even IOM , ???. A road race championship but no Irish road race  !!! - just a marketing ploy to capture some TV money. Even the TT itself doesn't sit comfortable with what they are proposing - how are you going to compact the TT into a weekend to make it TV friendly.
Will the rest of the races be shown live , but not the TT. The island weather is hardly TV friendly and what if there was a live crash - do you just turn off the live stream and say nothing for 2 hours (how accidents are currently dealt with).
Have the hotels, B&B's  etc been consulted - TT to be reduced to a long w/e. What about all the marshals who give up their time for nothing - how will they be accommodated? Will the ACU be as accommodating with dates , clearing 2 weeks out of the BSB calendar every year to facilitate the TT.
The more you look at this world TT series , the more one event sticks out as been different. How can you set up a series based on the exception? Be careful that you don't get what you wish for - a watered down TT...................
