Many people already do this. Crossdressers, drag queens, etc. all express part-time crossgender behaviors or identities with little to no body modification.
As far as "negative aspects of transition" you are going to get those regardless. If you transition, people will just see you as a man who underwent extreme body modification. If you don't transition, people will just see you as a man in a dress.
If you were born male, then presenting yourself as female is likely to cause "negative aspects" regardless of what manner you do it. Trying to avoid the judgment of others is a very bad reason not to use hormones or surgery. If you want to find an excuse not to transition, there are a lot of better excuses out there, such as costs and risks. For example, I'm adamant about not having any kind of surgery, because I think it's too dangerous.
For me, transition is very much an issue about the body. But if all you care about is how you express yourself, then go for it. There's no reason to drastically alter the body if it isn't necessary for you to do so.
