Sure, you can invent your own definitions,

Do I really need to remind you again that the meter has been abolished
as a primary standard, and that all length measurements
must (by the definition of the meter) be calibrated in seconds?

The dimensions 'time' and 'length' are different, hence you cannot
define units of length by units of time.

 Again, your 'are' is wrong.
What you should say is:
'my preferred dimensions of length and time are different'
 Again again, a 'dimension' is NOT a property of a physical quantity,
it is a property you assign to it, in any way you please.
(as long as you are consistent about it)
 

No!

"There is a difference between dimensions and units. A dimension is a measure of a physical variable (without numerical values), while a unit is a way to assign a number or measurement to that dimension.
For example, length is a dimension, but it is measured in units of feet (ft) or meters (m). "
