Title: No outputs

Is it possible to form a valid transaction that gets into the blockchain that has no outputs. I.e. all of the inputs go to fees.

No. You cannot have no outputs, however you can have an output with a zero amount so that all the Bitcoin still goes to fees.

Is such a tx "standard"?

(i.e. would normal nodes propagate it?)

If you use OP_RETURN I think it will be standard.

OP_RETURN (one per tx) is standard output
tx example:

Thanks amalcin. That is a very good example of what I am talking about.
But could you ever get an transaction accepted with , "out":[], "lock_time";0,.... ?

Such "transaction" can be created.
But it can not be confirmed or even relayed under the current consensus rules.

The transaction without inputs and outputs:

Code:

01000000000000000000

Decoded:

Code:

{
   "lock_time":0,
   "size":10,
   "inputs":[
      
   ],
   "version":1,
   "vin_sz":0,
   "hash":"d21633ba23f70118185227be58a63527675641ad37967e2aa461559f577aec43",
   "vout_sz":0,
   "out":[
      
   ]
}
