Not if (and I know if it is a BIG if) they keep the LCA modest and slim - no better than a M2k-5 sensor/avionics wise, and without the ability to carry as much. Sort of Gripen A or just stick to Mk1 standards. MMR, Derby/Astra BVRAAM and R73/Python SRAAM with the Dash V kit.
What that means is that we can have a finalized version of the LCA by mid 2013 - use the initial 40 GE engines to power at least 1-2 sqds, and by the time these are brought online (2016-17?), get the Kaveri 9 ton version working with the help of Snecma (in a worst case scenario, if the kaveri with the Snecma core is not ready, use the M88.4). Yes, the bird probly won't be as capable as a 414 powered version, but it'll be good enough to be ordered in large numbers and form the inexpensive base for the IAF.
This might actually be a faster route considering that the currently planned mk2 version is hardly off the ground as yet, and will require pretty distinct structural changes to get it up and running - I think AM Rajkumar had mentioned making the mk2 entailed at least a 25% change from the mk1, and the bird would optimistically operational only by 2018-20.
With a smaller engine, pumping just about 90kN, the current LCA mk1 might not need as many changes and be ready faster. The aims should be modest - slightly lighter (~ 6000kg) and some increase in thrust over the IN20. Perhaps the IAF may have to compromise on some parameters such as payload, but this might work as a low end fighter that can be ordered in bulk.
IIRC, the F-404 was replaced by the M88 on the Rafale, so the French might have some experience and their consultancy could be used. But seriously, the US vendor's shenanigans do not inspire confidence. What if they decide on sanctioning the F414 in 2015, its a risk that cant be risked if the program has to be taken forward.
