Is there any chance someone could make a script that changes @username #hashtag strings sent in convos for a clickable string linking to the profile of that person in twitter and in a search request with that hashtag?

Example:

do you know @warmth? --> my profile
are you planning to go to #twiteq? --> search this hashtag in search.twitter.com


This idea can be very usefull and could become in a huge script later with many options, visualizations of pics, etc...
