When someone does something quite beyond the pale... then replies in unjustified confidence he has a hunch it'll be fine... well that does tend to define hubris at it's best. Regardless of the outcome.
If you speak as if you have ancient Chinese wisdom, you shouldn't be surprised at being asked for examples of your successes. I was sincere in my comment that I'm not given to sarcasm. I was also sincere that I was quite prepared to be impressed.
For my part I will acknowledge that I should apologize for the fact that I clicked into this thread from the front page without realizing which sub-forum it's in. That is indeed an important distinction. I do apologize for not knowing which forum section your post was in. I would have likely had a more tolerant sounding reaction to your thread and subsequent comments of hunches and theories why this will work. But some humility on your part for understanding that hunches don't make for good bonsai would also be grand.
I will give you an important piece of advice, since this is the new to bonsai forum - and even should you ignore this comment entirely, benefits the whole. When working with collected material.... Don't put the cart before the horse... let it live before planning it's life or imagining how you'll design it. This is often the hardest thing for people to grasp when working with collected trees... wait.
A collected tree often has to wait for years to get into a pot... so don't worry about that. I wouldn't move it out of the container you've put it in until at least it's second dormancy cycle (Fall of 2015)... and even then any work would only be to move it into a better container, with minimal root tampering.
The questions and approach I would advise in posting threads like this in the future is pretty simple.... having made the decision to collect in the hardest season for survival... ask how to care for it and best insure it's life.
There are a couple things you can do to work with trees in summer stress... sphagnum moss as a top dressing is very helpful.... but also depending if you can't be there to mist it several times a day over the coming months, then you should 'diaper' the trunk. This is accomplished by using absorbent strips of cloth (like towels) and wrapping all the trunk and main branches that you effectively can. Keep this damp at all times. The tree is able to transpire through the cambium layer and will allow the roots some time to recover. Wire is often used to secure the diapering material to the tree. A single wrap with a twist is enough to secure ends.
Also I'm not sure what soil medium you used, but straight pumice would be the best thing for it. If you have any, repot it into that immediately. I take it from your post that you just did all this work several hours ago. So taking that action right now would be fine. It would be detrimental in the near future though, so don't bother if you don't have any.
There are water soluable root enhancers with mycorrhizae you could water with which will also help promote root growth and health. I use this.....
It's called
Root Zone
