I would like to put frozen, thawed blueberries inside a red velvet cake roll filled with cream cheese icing. I am concerned that the blueberries may "bleed" or just look a mess instead of having the red white and blue look I am hoping for. Has anyone ever tried anything like this?

While you could probably do dried blueberries in a VERY low oven (150F), you'll most likely need to prop the door open slightly to allow moisture to escape. You'd be best to do them in an actual food dehydrator which will have a fan to expell the moisture being released from the food.
Keep in mind however that if dried as they are, they will shrivel up into fairly hard little bits. If your goal is something similar to the dried blueberries that you can buy in retail stores, they will have to be treated in a sugar syrup to maintain the chewy texture and keep them from totally drying out. I'm not sure if the commercial producers are first drying and then soaking in a sugar solution and perhaps drying again so that the sugar is drawn into the cells of the berry. Whatever the case...commercial dried cranberries and blueberries maintain the chewy texture due to being treated with a sugar solution at some point.
If you are looking for ways to handle a bumper crop or bulk buy on blueberries, I would recommend freezing them and stick to buying commercially processed dried berries for the best results, least effort, and greatest bang for your buck.
I strongly believe it's no good any more.
Update after hearing some comments [2nd update]
When u see liquid in the bag, it means the temp is usually above zero C which means it isn't the ideal temp for frozen berries.
I think it's usually quite ok to keep in the fridge for a few days, but not weeks
[3rd update] I am sorry for whatever confused I caused and I removed the comments about liquid in my previous answer to avoid confusion when people see this post in the future. Anyway, I found a box of forzen berries and here is what the pack suggests.
Please don't eat the berries if they are in the fridge for more than a few days

Yes, the blueberries will bleed, and, what's even more non-4th-ish, they will make purple or lavender stains instead of blue.
If you are serving the roll rather quickly after assembly, consider thickening the pureed blueberries seperately with some corn starch or pudding mix. Then you can make a blue-and-white filling inside the red roll. The blueberries must be boiled and cooled again, obviously, because they would otherways melt your cream cheese icing. Aim for a "spreadable pudding when cool" consistency of the berries, ideally the same consistency as the cream cheese filling.
You can layer both fillings atop each other, but the risk of them mixing when rolling the log is high. I suggest piping alternating blue and white stripes parallel to the edge where you hold it / future long axis of the log and rolling very, very carefully. This should result in a blue/white pattern when you slice the log (wipe the blade often!).
The longer you store your log, the more colour will leach into the white, but a few hours should be ok. Chill thoroughly.
