can I lift the bloomed iris and place it where I want while it is in bloom
I would think that it would be a possibility, if you were to take a lot of soil, both deep and wide.

would it die from the disturbance?
The iris rhizome will not die, but the bloom may be in jeopardy in the move of toppling over or breaking off. At any rate, you will then have the colors where you want them for future years.

I'm wondering if it might be a better idea to pot them up this fall, and then sink the pot in the ground. Then if it blooms next season you could then move and sink the pot where you want it blooming, and then transplant it into the ground later next season.
Hopefully there will be others with ideas about it too.

You might want to also ask your question at The Iris Forum linked below. Not all 'bulb' folks are necessarily bearded iris folks.

Here is a link that might be useful: Iris Forum

Bearded or other rhizomatous iris are best transplanted/divided/moved when root growth slows and they begin to enter dormancy in late summer or early fall.

Remember that bearded iris should be planted quite shallowly so that the top of the rhizomes are exposed to the sun. Often, gardeners will form a small "mountain" of soil and position the rhizome at the top of the mountain with the roots draping down on all sides. Plant in very well draining soil in as much sun as possible and divide when the plants start to become crowded or slows down bloom production - around every 3-5 years. Other than that, they require minimal attention :-))
