Welcome, if you do the training and build up gradually then you have every chance. Cycling is much less taxing on the body than running.
Just make sure your form is ok, don’t develop bad habits, stick to the plan. Definitely start in base and potentially do a double dose of base to give your body more time to adapt to training.
Put a little focus on nutrition, nothing crazy but make sure you are eating properly to support the training. You shouldn’t be smashed after a short commute.
The above should fit with what you’re trying to achieve and targeting 3w/kg is not shooting for the moon. You’ll get there!
