I think it can definitely work, aslong as you have some space (ie. office) thats out of harms way there should be no issue.
Also you might have to look into OH&S standards just to make sure everything is above board. (but as it's your own baby i highly doubt you would allow unsafe practices).

DP's cousin owns her own business (batteries) it can be a very dangerous place for kids BUT she had a port-a-cot setup in her office, she put gates on doors when the kids were older and followed all OH&S rules with her kids & her staff, there were no issues at all and she found time to manage the business and be with her kids.. the best of both worlds really.
