From Indiana to RMNP you are looking at 2 long days driving. From there to YNP/Teton you are looking at another long days drive. And from YNP back to Indiana is another 3 long days driving. By long days, I mean in excess of 8 hours actual driving time plus any rest/food/fuel stops per day. (Per google maps and assuming Indianapolis) Right off you are losing at least 6 days to travel. That leaves 8 days (3 each for RMNP and YNP and 2 for Teton?) with no time for any rest. Doable? Yes. Enjoyable? Decide for yourself.
