Not yet. This last year NHRA added some new combinations for the Challenger where showroom or street configurations of the 5.7, 6.1 and 6.4 hemis are legal. They haven't approved the street 6.2 supercharged hemi to date. However, the race only 2015 Challenger Drag Pak that came out this year can be ordered with either an NA 426 hemi combo or a 354 supercharged hemi combo. They had to reduce the cubic inches of the supercharged hemi to match the Ford and Chevys. The race ready supercharged Drag Pak will only set you back $110,000.
