Good question,sadly I do not have any definite answer at the moment.

But why new BVR if you already have many available in your inventory? Is Russian BVRs not compatible with LCA? Also MICA will come with Rafael they are also good too.
@Basel too
Mica
GOI cleared the proposal to buy close to 500 MICA, a short and medium range air-to-air tactical missile manufactured by the French company, MBDA, for around Rs 6,600 crore. The government had earlier approved the Mirage
upgrade deal
Now logically for 51 mirages 500 mica looks a bit too much. But i believe a part of these may be shared with Rafales (coming in whenever) in future
So perhaps we may not see Mica with LCA.
Russian R77 SD/MD perhaps similarity to Astra Mk1/2.
Derby/Python
The ground integration of the Israeli-made Python-5 too has been completed. Derby has also been integrated on to the aircraft. Tejas can carry two SR- AAM/ R73/Python 5 at the extreme end pods. The Derby (two missiles) is being integrated on the mid-board-pods of Tejas
Logically R77 should be integrated with LCA but due to some historical issues with handling and storing of R77, i dont know if they are so actively used as envisioned when procured. Today anyways there seems to be a better mix of options available ..I believe Mig29K and Su30MKI are using it. PSK said about R77 issues as
The service life of the R-77 and AMRAAM are the same. But there is one critical component within each of these BVRAAMs that needs periodic servicing: the NiCad batteries responsible for supplying power to the active seeker and actuators. The NiCad battery typically has a shelf-life of eight years, but needs periodic testing at least once every year. For the R-27R/R family of BVRAAMs too the same is the case with the batteries, in addition to the cryogenic cooling system for the IR seeker (for the R-27T and R-73E). After checking up with the OEM (Vympel JSC), I've been informed by the OEM that the problem area is the on-board NiCad battery pack. To make matters worse, such NiCad batteries have not yet been indigenised despite the existence of in-house capabilities (HBL-Nife and High Energy Batteries being the two industrial entities that are currently supplying NiCad aircraft/missile batteries to the DRDO and armed forces).
And CAG rapped IN when they bought R77 just few in numbers (lol)
So obvious choice of replacing at least R77 is via Astra Mk1/2, so i see a more potential chacne of Astra integration in LCA over time
