Mr. The Kid-
Short answer: No.
There are some possible mechanical difficulties with doing this. For example, after you pull the bullet, the neck of the brass will spring back to a diameter smaller than the bullet. Inserting another bullet will be a problem, and may require some neck expansion to accomplish. After you have inserted the bullet, there will be required some crimping operation to hold the bullet in place sufficiently to withstand the slam-bang of the loading cycle.
A possibly dangerous difficulty is that type and amount of powder used in the factory load may not be correct for the replacement bullet. The powder type is not something you can look up in a reloading manual, so adjusting the factory amount for your substitute bullet is not possible. Just plugging in another bullet may result in a dangerous overload, or a poor performing underload. Using bullets of equal weight may not avoid the problem, because pressures can be really different for different types of bullets even though they weigh the same.
There exist some possible solutions to your problem of obtaining unleaded ammo. You might contact some of the licensed, reputable custom loaders, and ask whether they can make what you need. It's likely not to be cheap. You can find the some of them online, or perhaps by inquiring locally. If they don't have the FFL that allows them legally to make and sell ammo, I'd avoid them.
For liability and other reasons, neither would I want to ask a reloading friend to assemble the lead-free ammo. An oopsie could destroy the friendship, not to mention a firearm.
